Description
Technical field:
This utility model relates to a kind of disposable medical with the oxygen therapy apparatus, specifically is a kind of integral type sterile oxygen absorbing damping device.
Background technology:
At present, the integral type sterile oxygen absorbing damping device that generally adopts in the hospital generally comprises humidification bag, humidifying pipe, oxygen output pipe, is connected the formula that the fractures switching mechanism that blocks water film filter and be used to connect oxygen output pipe and humidification bottle intracavity on the humidifying pipe; Described humidifying pipe is positioned at humidification bag inside; In addition, enter in the humidification bag and pollute humidification liquid along oxygen output pipe in order to prevent antibacterial that oxygen output pipe is suspended the external world when using, prior art integral type sterile oxygen absorbing damping device has also connected a non-return valve on oxygen output pipe; Described non-return valve is a silica gel tube, and described silica gel tube is provided with closed slit on its barrel under naturalness, when being subjected to the gas pressure of humidification bag internal oxygen gas, and silica gel tube meeting distending, thus impel gap opening, oxygen can be flowed out by aperture slots.Because the silica gel tube exists one to use fatigue strength, in other words, the silica gel tube can follow the string because of tired, therefore cause the slit on the barrel to be in open state all the time, thereby influence the sealing effectiveness of damping device, cause extraneous antibacterial to enter in the humidifying container and pollute humidification liquid from silica gel tube gap opening.
The utility model content:
The technical problems to be solved in the utility model is to provide a kind of sealing property better, thereby can effectively avoid extraneous antibacterial to enter into the intravital integral type sterile oxygen absorbing of humidification bottle damping device.
Technical solution of the present utility model is, a kind of integral type sterile oxygen absorbing damping device with following structure is provided, and it comprises humidifying container, the film filter that blocks water, humidifying pipe, oxygen output pipe, be contained in the switching mechanism of oxygen break-make in non-return valve on the oxygen output pipe and the control oxygen output pipe; Described humidifying pipe bottom is connected with foam maker; Described foam maker is positioned at humidifying container; Described humidifying container is a bottle, is connected with bottle cap on the described bottle; Described bottle cap is provided with the passage that is communicated with humidifying container inner chamber and oxygen output pipe; Described switching mechanism is positioned at described passage; Described non-return valve comprises valve pocket, spool, spring and sealing ring; Described valve pocket is enclosed within the spool outside; Described spool and valve pocket are movingly; Described valve pocket is connected intracavity in the oxygen output pipe; Described spring one end withstands on the spool, and the other end withstands on the valve pocket; Described sealing ring is enclosed within on the spool; Described valve pocket right-hand member is provided with the sealing surface that matches with sealing ring.
After adopting above structure, compared with prior art, the utlity model has following advantage: different because of influenced by silica gel tube fatigue strength to cause slit on the silica gel tube barrel to be in open state all the time with non-return valve of the prior art, because the sealing ring in this utility model all is pressed on the sealing surface of valve pocket right-hand member at conventional state by spring, in other words, sealing ring can both be close to the sealing surface of valve pocket right-hand member under the effect of spring force and close, having only when spool is subjected to certain gas pressure can open channel, therefore, compare with the silica gel tube, this utility model newly has better sealing property, thereby can effectively avoid extraneous antibacterial to enter in the humidification bottle.
As a kind of improvement of the present utility model, the described film filter that blocks water is positioned on the bottle cap and can be as a whole with bottle cap.Owing to adopt Luer lock to be connected usually between block water film filter and the oxygen output pipe in the routine techniques, this connected mode is in use or in the transportation, be easy to cause block water loosening situation takes place between film filter and the oxygen output pipe, one loosening will gas leakage, and medical personnel need with hands go tighten when leaking gas at every turn, therefore, it brings unnecessary trouble for medical personnel's use.Between film filter and the oxygen output pipe gas leak phenomenon takes place for avoiding of the prior art blocking water, make things convenient for operation of medical workers, to block water film filter and bottle cap of this utility model made an integral body, whole setting not only makes this utility model in use, can not occurring blocks water between film filter and the bottle cap gas leak phenomenon takes place, saved the manual troublesome operation of tightening the film filter that blocks water of medical personnel, and, because whole setting has significantly reduced number of components and parts, therefore, processing cost of the present utility model has also obtained reducing widely.
As another kind of improvement the of the present utility model, described switching mechanism comprises a rotary handle and is connected and the whether rotating shaft of energy control channel break-make with rotary handle; Described rotating shaft and bottle cap are rotatably connected; Described rotating shaft is provided with a radial direction through hole that communicates with passage.Prior art adopts the formula switching mechanism that fractures to control oxygen output pipe usually and communicates with the humidifying container inner chamber, we know, the switching mechanism that fractures can only disposablely use, changing sentence speaks, just oxygen output pipe and humidifying container inner chamber can be connected after the switching mechanism that fractures is fractureed, and after oxygen output pipe and the connection of humidification bottle intracavity, can't again they be sealed, especially in the time of in use need in time closing oxygen output pipe for those, very trouble can become.Because this utility model switching mechanism comprises rotary handle and the rotating shaft that is connected with rotary handle, therefore, medical personnel can come oxygen output pipe is opened or closed at any time by the operation rotary handle, thereby convenience are provided for the patient of intermittently oxygen uptake.
As another improvement of the present utility model, described foam maker can adopt the white fused alumina material.Because the quantity of micropore is generally more than 1000 orders in the white fused alumina material, its aperture is very little, thereby Oxygen Flow goes out the noise that foam maker produces can reduce foam maker work greatly the time.
As last a kind of improvement of the present utility model, can be provided with a medicine-pouring port on the described bottle cap; A silica gel plug is housed on the described medicine-pouring port.For some patients who needs adding liquid medicine in the humidification liquid when the oxygen uptake, medical personnel can directly be inserted in injection needle on the silica gel plug by medicine-pouring port, thereby make things convenient for medical personnel to inject liquid medicine in humidification liquid.
